UNITED STATES PATENT OFFICE.

CHARLES E. DOBSON, OF NEWV YORK, N. Y., ASSIGNOR TO HENRY BENARYS BAN ME PLACE.

SPECIFECATION forming part of Letters Patent No. 338,142, dated March 16, 1886.

Application filed June 2, 1885. Serial No. 16135 13. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES E. DoBsoN, of the city, county, and State of New York, have invented certain new and useful Improvements in Banjos, of which the following is a full,

clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a face View ofa banjo to which my improvement has been applied, part being broken away. Fig. 2 is a sectional side elevation of a part of the same.

The object of this invention is to provide banjos constructed in such amanner that they will produce sweeter and clearer tones than banjos constructed in the ordinary manner.

The invention consists in a banjo constructed with the forward edge of its rim spun over a wire ring, and the said spun-over edge and rim provided with numerous perforations parallel with the aXes of the said rim and ring and registering with each other, as will be hereinafter fully described, and then claimed.

A represents the rim of a banjo, the rear edge of which is spun over a bead formed on the rear edge of the wood B. The forward edge of the rim A is spun over a wire ring, 0,

so that the said wire ring will be inelosed in the said edge, and thespunover edge and ring are then perforated with numerous holes, as

at a, parallel with the axes of the said rim and ring and registering with each other. The head D is then drawn over the spun-over edge 5 of the rim A, is folded back around the flesh hoop E, and is strained by means of the hoop F, hooks G, and brackets H in the ordinary manner. By this improvement a sweeter and clearer tone will be given to the instrument, and better effects can be obtained than with an instrument construct-ed without the said improvement.

I am aware that the forward edge of a banjorim has been spun over awire ring; also, 5 that the parchment has been arranged to rest upon a resonant ring supported on the forward edge of the banjo, and I do not claim such as of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A banjo constructed substantially as herein shown and described, with the forward edge of its rim spun over a wire ring. and thespun 5 over rim and wire ring provided with numerous perforations parallel with the axes of the said rim and ring and registeringwith each other, as set forth.

CHAS. E. DOBSON.
